Medium-sized, long-tailed, sluggish bird that occurs in a variety of humid forest types. Males are iridescent blue with a yellow belly; females are mostly grayish where males are blue. Yellow eyering visible at close range; note finely barred outer tail feathers. Sits still and makes abrupt short flights to forage on large insect prey; also eats fruit. Song is a quick series of barking notes. Similar to Green-backed Trogon, but slightly smaller with a complete eyering, different tail pattern, and faster song.
